Hi Jim1,
Welcome to the Community!
We'll still take you on as a customer and you'll also receive a feed-in tariff for any power you export to the grid irrespective of the size of your system. However, the size of your system can impact which discount plans you are eligible for. For example, our current Solar Savers plan which gives customers a boosted FiT of 20c/kWh is only available to customers with systems no larger than 10KW.
Kind regards,
Jayden
